这些在约束*键*等方面有什么区别?
选择进入语句
SELECT column1, column2, someInt, someVarChar
INTO ItemBack1
FROM table2
WHERE table2.ID = 7
插入语句
INSERT INTO table1 ( column1, column2, someInt, someVarChar )
SELECT table2.column1, table2.column2,
FROM table2
WHERE table2.ID = 7
并且
Create table ramm as select * from rammayan
